Hi I might not be the best person to answer this,I'm not a comp wiz, but i used to have that problem when i ran MacOS9. I assume your Running a Mac Right? The reason i think this is happening is because you have Virtual Memory on.Try turning Virtual Memory off and try running the app again.It's also a good idea if running photoshop with virtual memory on that you have a good amount of hardrive space. I don't know if that helps but it worked for me for a while. But remember that with virtual memory off you wont be able to run more that 2 programs at the most on the mac. I got really tired of this that's why i went and bought a pc,It solved that problem but now i have others. I guess one just has to have patience when it comes to computers
